CEMENT-BRICK MACHINE.

Specification of Letters Patent.

Patented Jan. 2, 1906.

To all whom, it may concern.-

Be it known that I, FRED B. DYSART, a citizen of the United States, residing at Superior, in the county of Nuckolls and State of Nebraska, have invented certain new and useful Improvements in Cement-Brick Machines, of which the following is a specification.

This invention relates to improvements in machines for making blocks from cement, sand, &c. in plastic form.

The especial object of my improvements is to produce a machine of this character which will make, under sufficient pressure, a large number of blocks quickly and facilitate the removal of same when they have been properly molded.

The machine which forms the subject-matter of this application is adapted to be operated by hydraulic power; but the particular hydraulic appliances form no part of my invention and may be of any well-known or preferred construction.

In the accompanying drawings, which form a part of this application, Figure 1 is a side elevation of my improved machine. Fig. 2 is an end elevation of the same, and Fig. 3 is a cross-section on the line 3 3 of Fig. 1.

Referring to the details of the drawings, 1 represents the base of the machine, which is rectangular in its general form and may be made of any suitable material.

2 represents four upright shafts or rods secured in the respective. corners of the base and having their upper ends threaded to receive the adjusting and holding nuts 15.

- 3 represents the bed-plate of the machine, which is provided at its four corners with suitable boxes 3, which provide slidable bearings on the shaft 2. The bed-plate is secured to the upper end of the piston 6 which works in the hydraulic cylinder 6 in the usual manner. Placed above the bedplate 3 are the mold-boxes 4, of which two are preferably employed, and same are secured on a frame 4 to the corners of which are bolted boxes 4*, which form slidable hearings on the shafts 2. These mold-boxes are provided with chambers 4 which are suitably spaced apart by partitions, and said chambers are open at the top and bottom.

The top plate or header 5 is adjustably mounted on the shafts 2, the latter passing through suitable openings in the corners of the headers, and is held in place by the nuts 15 on the shaft 2. Secured to the upper side of the header is a cylinder 7, provided with a suitable piston adapted to be operated by air or other fluid entering through the pipe 13 from any suitable source of supply. Secured to the under side of the header are a plurality of dies or plungers, the same being bolted to the header and provided on their under side with face or die plates of any de sign desired. These plungers are proportioned to enter the chambers 4 of the moldboxes. Passing through suitable openings in the ends of the header are slotted links 8, the lower ends of which are secured to the ends of the mold-box frame 4 andthe slot of which is engaged by the lowerend of the lifting-rod 9, the upper end of which is secured to the longitudinal beam 11, which is supported by the upper end of the piston of the cylinder 7. Suitable braces 12 extend from the lifting-rods to the beam 11 and serve to brace and strengthen same. Sufficient space is left between the bottom of the mold-boxes and bed-plate 3 to insert wood pallets 16, the latter forming removable bottoms for the mold-boxes. The cylinder 6 is supplied with a pipe 14, which is connected with any suitable source of supply of motive fluid for operating the piston of said cylinder. I

In a machine constructed substantially as described, assuming that the mold boxes have been filled with material to be molded, the piston 6 being raised by a suitable power applied thereto the mold-boxes will be pushed upwardly until the cement comes in contact With the plates secured to the lower side of the dies 10, when the piston will be stopped and held in such position, whereupon the upward movement of the mold-boxes will be continued by applying power to the piston of the cylinder 7, and said piston will thereby be raised, carrying with it the beam 11, the rods 9, and the slotted links 8, and thus elevate the mold-boxes a distance suflicient to permit the dies or plungers 10 to push the molded blocks of cement from the chambers 4 down upon the pallets 16, with which said blocks will be removed while resting on the pallets. The mold-boxes will be filled with cement or the like in plastic form by shovels or in any suitable manner.

It will be noted that the stroke of the respective pistons of the cylinders 6 and 7 may be regulated and that through the adj ustability of the header 5 by screwing up or down the nuts 15 the relative action of the moldboxes and dies may be adjusted and controlled.

Having thus deserib ed my invention, What I claim as new, and desire to secure by Letters Patent, is

In a machine for making blocks from material in plastic form, a bed-plate slidably mounted on a suitable frame, mold boxes slidably mounted on said frame above said bed-plate, means for raising said bed-plate 'and mold-boxes, a header adjustably mounted on said frame, dies secured to the under side of said header, and means for raising said mold-boxes independently of said bedplate.

In testimony whereof I affiX my signature in presence of two Witnesses.

FRED B. DYSART.
